A tiny minority. The vast majority of climate-competent scientists
agree global warming is man-made and is a serious emergency. Sure
there are crooked oil-industry scientists just like there were crooked
tobacco industry scientists. There's a lot of oil money for lying to
the public by denying the fact of human-caused global warming.

At any rate, it's almost beyond question that humans are causing it.

Anyone who thinks that 6 billion people can't have an effect on this
planet need to learn how to think!

Every industry tends to play up the good and play down the bad. You'd be
surprised at how often that really happens.


Part of the problem is that humans, as a species, tend to egocentricity.
Anything else is based upon what we as individuals find appealing. We really
have trouble with the concept of there being 6 billion others that all add
up to cause global change. If population continues to grow at the rate it
has for the past 50 years (it's doubled in that time), there will likely be
a vast increase in pollution levels (both air and water) and a severe
shortage of food to feed everyone. The planet has only so many resources,
and unless we have developed FTL space travel, once those are gone, so are
we..




Most people have problems comprehending the really large numbers. We use
A.U. to represent 150 million km (93 million miles) and the mole in
chemistry to deal with a large number of particles (6.022x10^23). The
thought of 6 billion people is incomprehensible to most of us.

I have no doubt that there will be wars over clean water, arable land
and other resources.
